Buckle up and don’t forget to polish your glasses because today we’re getting nittier than gritty. Well, we all know that we people are so busy now-a-days so, We really don't have that time to sit and calculate anything without using a calculator.So, here a calculator will save our time by increasing the speed. What we’re really going to talk about is all these IP/subnet Calculator you’ve seen popping up everywhere. But we need to know what they are really good for. Well, i am going to tell you just about everything you’ll need to know about an IP address or block of IP addresses.For instance, do you know what the subnet mask of the IP address “192.168.0.1?” Well, you could calculate it out longhand (which we’ll show you how to do) or you can just plug it into a subnet calculator and have it do all that hard work for you. Afterall, that’s why we invented computers in the first place, right? So, let's get to know why we use an IP calculator. IP CALCULATOR: An IP subnet calculator is a tool, normally an online tool, which performs a series of calculations based on specific values and returns the results. So far, so normal calculator. Only this calculator is for working out network values.The values given are an IP address and a netmask.to calculate and return the following information: 1.Network, in IP/Netmask form. 2.Network mask. 3.Binary subnet mask. 4.CIDR subnet mask. 5.Network wildcard, or part of the usable IP addresses. 6.IP class. 7.Network address, the IP of the network itself. 8.Broadcast address. 9.Host address Range. 10.Total number of hosts. We’re going to take a look at how you use an IP calculator to get information about your office network. For example, if a PC’s IP address is 117.206.203.198 and you have a 15-bit netmask, the calculation will give us the values which are shown on the above part. Now We going to know about the IP address in detail. IP ADDRESS: The Internet is a collection of networks whose users communicate with each other. Each communication carries the address of the source and destination networks and the particular machine within the network associated with the user or host computer at each end. This address is called the IP address. Although IP stands for Internet Protocol, it's a communications protocol used from the smallest private network to the massive global Internet. An IP address is a unique identifier given to a single device on an IP network. An IP address is a 32-bit number that is separated by decimals into four 8-bit groups, called octets, which are separated by decimals. The numbers in each octet can range from 0 to 255. IP address: 117.206.203.198 This address will serve as our original network identifier (network ID); it is the IP address that identifies the larger network that we have used earlier. SUBNET: A subnet (short for "subnetwork") is an identifiably separate part of an organization's network. Typically, a subnet may represent all the machines at one geographic location, in one building, or on the same local area network (LAN). Having an organization's network divided into subnets allows it to be connected to the Internet with a single shared network address. Without subnets, an organization could get multiple connections to the Internet, one for each of its physically separate subnetworks, but this would require an unnecessary use of the limited number of network numbers the Internet has to assign. It would also require that Internet routing tables on gateways outside the organization would need to know about and have to manage routing that could and should be handled within an organization. The smallest subnet that has no more subdivisions within it is considered a single "broadcast domain," which directly correlates to a single LAN (local area network) segment on an Ethernet switch. The broadcast domain serves an important function because this is where devices on a network communicate directly with each other's MAC addresses, which don't route across multiple subnets, let alone the entire Internet.MAC address communications are limited to a smaller network because they rely on ARP broadcasting to find their way around, and broadcasting can be scaled only so much before the amount of broadcast traffic brings down the entire network with sheer broadcast noise. For this reason, the most common smallest subnet is 8 bits, or precisely a single octet, although it can be smaller or slightly larger. Subnets have a beginning and an ending, and the beginning number is always even and the ending number is always odd. The beginning number is the "Network ID" and the ending number is the "Broadcast ID."It purpose is to designate the listening address for all devices on the subnet. When someone wants to send data to all devices within a subnet, the use the subnet’s Broadcast ID. So,that's subnet! pretty understandable! isn't it? Now, let me tell know what is subnet masking. SUBNET MASK: An IP address alone does not provide all of the information necessary to begin subnetting (dividing a network into smaller subnetworks, or subnets). This is where the subnet mask comes in. A subnet mask, like an IP address, is a 32-bit number separated into four octets. The purpose of the subnet mask is to differentiate the portion of an IP address that is used to identify the network from the portion used to identify the hosts. The subnet mask plays a crucial role in defining the size of a subnet.Whenever you're dealing with subnets, it will come in handy to remember eight special numbers that reoccur when dealing with subnet masks. They are 255, 254, 252, 248, 240, 224, 192, and 128. You'll see these numbers over and over again in IP networking, and memorizing them will make your life much easier.

BINARY SUBNET MASK:Binary is all zeros and ones, as I’m sure you’re aware of it. A subnet mask converted into binary is no different. However, all zeroes are placed on the right while all ones are placed on the left.

CIDR SUBNET MASK:A system called Classless Inter-Domain Routing, or CIDR, was developed as an alternative to traditional subnetting. The idea is that you can add a specification in the IP address itself as to the number of significant bits that make up the routing or networking portion.

For example, we could express the idea that the IP address 117.206.203.198 is associated with the netmask 255.254.0.0 by using the CIDR notation of 117.206.203.198/15 This means that the first 15 bits of the IP address given are considered significant for the network routing.IP CLASSES:

1-127-class A

128-191-class B

192-223-class C

224-239-class D

240-254-class E

Conclusion:Hopefully by now, you should have a working understanding of some of the networking implications of the IP protocol. While dealing with this type of networking is not always intuitive, and may be difficult to work with at times, it is important to understand what is going on in order to configure your software and components correctly. So here is the IP CALCULATOR that will help you understand some of these concepts and get the correct addresses and ranges that you need by typing in certain information. Here, you can find a subnet calculator which will provide you a CIDR range finder, and an IP address to binary octets converter, IP class finder, network address, broadcast address, number of hosts etc. You can easily get the results from here. Use this tool to help you when making networking decisions.by Editor.
